The prevalence of saphenofemoral incompetence in a series of 105 consecutive patients undergoing saph‐enofemoral ligation as part of an operation for primary varicose veins was determined using a directional continuous‐wave Doppler ultrasonic device. Saphenofemoral incompetence was correctly predicted in 97% of limbs. Using conventional clinical methods, incompetence was correctly predicted in 82% of limbs. This difference was highly significant (P < 0.01 McNemar). It is concluded that a directional Doppler ultrasonic assessment is a useful aid in the pre‐operative determination of saphenofemoral incompetence.
